| 摘 要： | 针对落地原油的回收及土壤污染治理问题，提出了用热碱水溶液清洗－气浮分离的处理方法，获得了比较理想的结果。实验中考察了清洗过程的反应温度、清洗时间、液固比、碱浓度及气浮温度和气浮时间等各种影响因素，得到了适宜的处理工艺条件。在此处理条件下，可使含稠油１２．５％的模拟含油土壤的油去除率达到９２．５％～９３．５％，土壤中残留含量降至０．９％～１．０％．提出的处理方法，能原消耗较低，碱剂费用仅为７元／ｔ（ｔ土）左右，且可以回收洗脱出来的原油。

| Abstract: | The paper presents a hot alkaline solution cleaning-floatation separa-tion method for treating crude oil contaminated soil and a better results has been ob-tained, The effecting factors concerning to the method including reaction temperature、cleaning time、ratio of liquid and soil、concentration of alkali as well as time and tempera-ture in floatation procedure have been investigated.Under the proper conditions obtained from the experiments,deoiling-rate of simulative oil-containing soil can be reached 92.5 ～93.5%while the concentration of residual oil in soil decrease to 0.9～1.0%. The en-ergy consumption is lower and the cost for alkali is only anout 7 yuan/(it soil).Crude oil cleaned down can be recovered |
